Definitions
- the invention relates to a frame, in particular a picture frame, with an anti-reflective glass plate, to the use of an anti-reflective glass plate, and to a process for making an anti-reflective glass plate, the glass plate having on at least a part of at least one of its surfaces a light reflection reducing coating.
- Untreated glass plates show a strong light reflection generally of about 8% when looking at the glass at normal angle (90°). The reflection increases sharply at sharper angles. This reduces the clarity of the picture, and is therefore unwanted.
- a known way to reduce the reflection is to etch one side of the glass plate to obtain an irregular surface, the irregularities having a distance between high and low points of about 300 nm to several micrometer. These irregularities are thus large enough to scatter reflected light in a diffuse manner. Thereby, the glass plate has anti-glare properties.
- a further known glass plate for picture frames is available from Denglass & Schott. That type of glass plate - as also described in US 5582859 - contains three coatings on each side of the glass in order to achieve the antireflective properties. Typically, SiO 2 ; TiO 2 , SiO 2 /TiO 2 layers cause destructive interference of reflected light from the various optical interfaces.
- One disadvantage of that system is its uneconomic production process, as the plate has to be dip coated three times, and baked three times. Further, the properties of the glass are very good if looked at normal angle, but its angle dependence requires further improvement.
- Aim of the present invention is to provide frames like picture frames and other in-house frames with an anti reflective glass plate which requires only one layer for achieving the anti-reflective properties.
- a further object of the invention is to provide frames with an anti reflective glass plate that has high optical transparency and clarity, precluding the problem of prior art anti-glare glass plates.
- Yet a further object of the invention is to provide a coating with a better angle dependency that the three layer prior art coating.
- the present invention provides an article for in-house use, comprising a frame and an anti-reflective glass plate, the glass plate having on at least a part of at least one of its surfaces a light reflection reducing coating, wherein the coating contains nano-size particles and a binder, the coating having an arithmetic average roughness of 2-50 nm, and having per reflective coated side a minimum reflection at a wavelength between 400 and 800 nm of about 2% or less.
- the present invention further provides for the use of an anti-reflective glass plate in in-house applications, the glass plate having on at least a part of at least one of its surfaces a light reflection reducing coating, wherein the coating contains nano-size particles and a binder, the coating having an arithmetic average roughness of 2-50 nm, and having per reflective coated side a minimum reflection at a wavelength between 400 and 800 nm of about 2% of less.
- the present invention furthermore provides for a process of making a glass plate for an article for in-house use, the process comprises the steps of
- the transparency of the anti reflective glass plate is high.
- the transparency is generally about 94% or higher at 2 mm thickness at wavelength between 400 and 800 nm, preferably about 96% or higher, more preferably about 97% or higher, most preferably about 98% or higher.
- a frame as used in the present application is a structure to hold the glass plate at a fixed place.
- it consists of clamps at at least 3 places of a glass plate (e.g. two top corners and in the middle of the bottom of a square glass plate.
- the clamps are at all corners of the glass plate.
- the frame consists of at least a partial enclosure for the glass plate.
- at least two sites of the glass plates are enclosed, more preferably two opposite sites. Often all sites are enclosed by a frame.
- the frame can be of metal, wood, plastic or the like. Any known frame material can be used.
- the frame is a picture frame, the word picture being broadly interpreted as comprising photo's, paintings, posters, etches, drawings and the like.
- the frame is a show-case, comprising on at least one side a glass plate according the invention.
- a glass plate is contemplated by the inventors to have a wide meaning, including quartz, polycarbonate or other plate like materials that have a high transparency, preferably a transparency of about 80% or more at 2 mm thickness, more preferably about 90% or more at 2 mm thickness.
- the glass plate has a thickness of 0.5 mm or more, preferable 1 mm or more, most preferably, about 1.8 mm or more. In general, the glass plate has a thickness of about 10 mm or less, preferably 6 mm or less, more preferable about 4 mm or less, and most preferred, about 3 mm or less. However, the thickness of the glass is not critical, and could be 10 cm or less.
- the glass plate is organic, for example polymeric such as polyethylene naphthalate (PEN), polycarbonate or polymethylmethacrylate (PMMA), polyester or another polymeric material with similar optical properties.
- PEN polyethylene naphthalate
- PMMA polymethylmethacrylate
- the plate is first coated with a UV curable hard coat such as is known in the art in for example US4455205 , and is then coated with the anti-reflection (AR) coating. In this way the adhesion of the AR coating to the substrate is improved and the scratch resistance of the entire system is improved, particularly where the plate is an organic material such as a polymer.
- the substrate is inorganic. More in particular ordinary glass or quartz. Ordinary float glass is most preferred, as it is a cheap and widely available material
- An anti reflective glass plate is meant to be a glass plate (as defined) with a light reflection reducing coating on at least part of at least one side of the glass.
- the anti reflective glass plate will generally have a size of 10 cm by 10 cm or larger, preferably about 20 cm by 20 cm or larger. The maximum size is mainly dictated by practical consideration, and will generally be 2 by 3 meter or less. In one embodiment, the anti reflective glass plate preferably has a size of about 20 by 30 cm or multiples thereof, such as preferably 30 by 40 and most preferably 90 by 130 cm or the multiple thereof. In another embodiment, the anti reflective glass plate preferably has a size of about 30 by 40 inch (about 72 by 96 cm) or multiple thereof, such as for example about 60 by 40 inch (about 144 by 96 cm).
- At least part of the surface is coated with the anti reflective coating. Generally about 20% or more of the surface will be coated, preferably about 50% or more, most preferred, about 90% or more of the surface is coated with the anti-reflective coating.
- the anti reflective coating is such, that - measured for one coated side - at a wavelength between 400 and 800 nm (the visible light region) the minimum reflection is about 2% or less, preferably about 1.5% or less, and most preferably about 1% or less.
- the average reflection at one side, over the region of 400 to 800 nm generally will be about 2.5% or less, preferably about 2% or less, more preferred, about 1.5% or less, and most preferred about 1% or less.
- the minimum in the reflection will be at a wavelength between 400 and 800 nm, preferably at a wavelength of 450 nm or higher, and more preferred at 500 nm or higher.
- minimum is at a wavelength of 700 nm or lower, more preferred at 600 nm or lower.
- the optimal wavelength for the human eye is a minimum reflection around 550 nm as this is the wavelength (colour) at which the human eye is most sensitive. In case a colour shade is required, a minimum at lower or higher wavelength can be chosen.
- the reflection can be measured with any suitable reflectometer or colorimeter as known to the skilled artisan. Generally, the reflection will show a slope or a curve over the 400-800 nm wavelength. The minimum is defined as either a minimum in a curve, or the lower end of the slope, being at 800 or at 400 nm.
- the glass plate has an anti reflective coating on both sides. This may be achieved by coating both sides of a glass plate. It is also possible to laminate two glass plates which are coated on one side, whereby the non-coated sides are laminated to each other. It is preferred, that the glass plate in use has on both outermost sides an anti reflective coating, more preferred, an anti-reflective coating according this invention. It is, however, also possible to combine different techniques to obtain anti-reflective or anti-glare properties.
- one side of a glass plate is coated with an anti reflective coating according the present invention, and the other side of the glass is laminated with a transparent film with an anti-glare or anti reflective coating, preferably a coating according the present invention; the coatings according the present invention may be the same or different in chemical composition.
- the film used to stick two glass plates together may be a UV absorbing film in order to lend UV shielding properties to the picture or image.
- the reflection of the glass plate (with a coating on two sides) at the wavelength exhibiting a minimum is about 3% or less, preferably about 2% or less, and more preferred about 1% or less.
- the average reflection over a 400-800 nm wavelength range is generally about 4% or less, preferably about 3% or less, and most preferred about 2% or less.
- a light reflection reducing (or anti reflective) coating is a coating that reduces the reflection of light from an article at at least one wavelength between 400 and 800 nm, as measured at the normal incident angle. Measurements are carried out on the coated and uncoated article. Preferably the reduction in reflection is about 30% or more, preferably about 50 % or more, more preferably about 70% or more, even more preferably about 85% or more. The reduction in reflection as expressed in a percentage is equal to 100x(reflection of the uncoated article - the reflection of the coated article)/ (reflection of uncoated article).
- the arithmetic average roughness can be measured by Atomic Force Microscopy (AFM) and is generally about 2 nm or larger, preferably about 5 nm or larger, more preferably about 10 nm or larger, most preferable about 20 nm or larger.
- the arithmetic average roughness generally will be about 50 nm or lower, preferably 45 nm or lower.
- the coating of the present invention generally exhibits voids in the coating thereby having a nano porous structure.
- the voids aid in obtaining anti reflective properties.
- the coating comprises about 20 volume% or more of void volume.
- Void volume is herewith defined as open space between the particle/binder in principle filled with ambient air.
- the voids represent about 30 volume% or more, even more preferred the voids represent about 40 volume% or more; most preferred, the voids represent about 50 vol.% or more.
- the coating exhibits voids in the coating of about 90% or less, in another embodiment about 80 volume% or less; and in a further embodiment about 70 vol.% or less.
- the framed glass plates with the anti reflective coating are for use in house. This means, that during the envisaged life of the framed glass, the glass is not exposed to prolonged, direct rain, sunlight, wind and the like. It has been discovered by the inventors, that the nano porous structure of the coating precludes actual extensive outside use, but that it very well withstands normal household cleaning processes with water, water alcohol mixtures, water detergent mixtures, water alcohol detergent mixtures and other common house-hold cleaning fluids. Examples of commonly used cleaning fluids are glassex® and windex® (isopropanol, water, surfactant, pH ⁇ 10-11), or fluids comprising acetone, methyl-ethyl-ketone, alcohol and water.
- the reflection may change with 0.1-0.4 %, but thereafter, the reflection remains virtually constant. It was unexpected that the nano porous coating does not tear or wear from even regular use of house hold chemicals.
- the coating exhibits a change in reflectivity of about 0.4% or less after 2 hrs immersion in glassex®, more preferable, the change is about 0.3% or less.
- the coating exhibits a steel wool resistance, as measured as shown in the examples, of A.
- the coating exhibits - after 2 hours immersion in glassex® - a steel wool rating of B or better.
- UV screening or blocking coating may be provided on the glass before applying the anti-reflective coating. This is preferred, because otherwise the nano porous structure and roughness character may decrease, and thereby the antireflective properties would be negatively influenced. However, if the UV screening coating does not substantially influence the anti reflective layer, it may be applied on the antireflective layer. UV blocking coatings are known to those skilled in the art, and are e.g. described in US5371138 .
- antistatic and/or low-e coatings are antistatic and/or low-e coatings; the low-e coatings being coatings that have a low emission of infra-red, thereby having low-heat emission through the glass plate.
- a number of light reflection reducing coatings are known, but non of these describe or suggest the use in frames for in-house applications.
- US-2,601,123 for example a glass lens or other optical element is disclosed, on which surface a coating comprising spherical particles is applied.
- spherical particles have one diameter, length and width are equal so that the aspect ratio is about 1, and generally about 1.1 or less.
- EP-A 1167313 a coated automotive glass shield is described, the coating being prepared by mixing non-aggregated silica fine particles and/or linear aggregated silica fine particles, a hydrolysable metal compound, water and a solvent.
- W02004/104113 a nano structured coating is described, prepared from a coating comprising nano particles having a reactive organic group on their surface, a solvent and optionally some further compounds with a polymerisable group.
- the process for making an antireflective glass plate for a frame for in-house use comprises the steps of
- cleaning is an important step, as small amounts of contaminant such as dust, grease and other organic compounds cause the anti reflective coating, or other coatings to show defects.
- Cleaning can be done in a number of ways, such as firing (heating up to 600-700 °C; applicable if an inorganic substrate is used); and/or cleaning with a cleaning fluid such as soap in demineralised water, alcohol, or acidic or basic detergent systems.
- a cleaning fluid such as soap in demineralised water, alcohol, or acidic or basic detergent systems.
- the glass plate is dried at a temperature between 20 °C and 400 °C, optionally with applying an air flow.
- the coating is thereafter provided on at least a part of at least one side of the glass plate.
- a number of ways are available to apply thin coatings on flat substrates. Any way of applying a wet coating suitable for obtaining the required thickness would be acceptable. Examples of suitable techniques are meniscus (kiss) coating, spray coating, roll coating, spin coating or dip coating. Dip coating is preferred, as it provides a coating at two sides of the plate, and gives a repeatable and constant thickness. Spin coating can easily be used if smaller glass plates are used, such as ones with 20 cm or less in width or length. Meniscus, roll or spray coating is useful for continuous processes.
- the coating generally has a thickness of 1-5 ⁇ m before drying.
- the required wet thickness is dependant on the solid content of the coating, and is not important as such.
- the thickness generally is measured after drying and curing, but may be measured after drying only, i.e. after evaporation of the non-reactive solvent(s).
- the thickness of the wet coating is influenced by the viscosity of the coating, and the dip speed in case of dip coating; each technique has its own - known - ways to influence the thickness of a coating.
- the thickness of the coating when substantially dry is generally about 300 nm or less, preferably about 200 nm or less, most preferred about 170 nm or less.
- the dry, uncured coating will have a thickness of about 30 nm or more, preferable about 50 nm or more, most preferably about 60 nm or more. Thickness is measured either spectroscopically (reflectometery or ellipsometery) or by directly observing a fracture surface by electron microscopy.
- the process comprises a further step, the coated glass plate being subjected to a quality control step after coating, but before curing the coating.
- the antireflective properties are well discernable although slightly different from the cured coated plate. For example, upon cure, the coating may shrink, causing a shift in wavelength at minimum reflection. If glass plates would be not within specifications, these plates can be taken out before curing, thereby saving the costs of curing. Furthermore, these plates can be cleaned, and used again in the process of the invention.
- the coating used in this invention comprises nano sized particles, a binder and a solvent
- suitable particles are particles comprising lithium fluoride, calcium fluoride, barium fluoride, magnesium fluoride, titanium dioxide, zirconium oxide, antimony doped tin oxide, tin oxide, aluminum oxide, and silicon dioxide.
- particles comprising silicon dioxide most preferably particles consisting for at least for 90 wt.% of silicon dioxide are used.
- the coating comprises particles having an average aspect ratio larger than 1.5, as the glass plate shows an advantageous low reflection of light.
- the aspect ratio of the particles is larger than 2, more preferably larger than 4, even more preferably larger than 6, even still more preferably larger than 8, most preferably larger than 10.
- the aspect ration will be about 100 or lower, preferably about 50 or lower.
- the sizes of the particles may be determined by spreading a dilute suspension of the particles over a surface and measuring the sizes of individual particles by using microscopic techniques, preferably scanning electronic microscopy (SEM) or atomic force microscopy (AFM). Preferably the average sizes are determined by measuring the sizes of 100 individual particles.
- the aspect ratio is the ratio between the length and the width of a particle. In case of rods and worm- like particles the length is the largest distance between two points in the particle and the width is the largest diameter as measured perpendicular to the central axis of the particle, both the length and the width are measured of the projection of the particles as observed under the microscope.
- Worm-like particles are particles having a central axis that deviates from a straight line.
- Examples of worm-like particles are known by the trade name Snowtex (IPA-ST-UP, particles have a diameter of 9-15 nm with a length of 40-300 nm), as delivered by Nissan Chemical.

Generally, the particles will have a size of 200 nm or smaller, preferably 150 nm or smaller, and most preferred about 100 nm or smaller. With respect to other characteristics, the description of the non-spherical particles described above is equally applicable to the spherical particles.
- the advantage of using largely spherical particles is that the volume nano-pores resulting from the space between spherical particles is small relative to the space between non-spherical particles and thus the coatings derived from spherical particles suffer less from filling of the nano-pores via capillary forces leading to a loss in anti-reflective performance.
- the coating comprises mixtures of above described particles.
- the coating comprises a binder, which has as main function to keep the particles attached and adhered to the glass plate.

- the binder preferably polymerises itself to form a continuous polymeric network.
- the binder of the coating consists substantially of an inorganic binder, as such coating shows very good mechanical properties and good adhesion to the substrate, resulting in for example high puncture resistance, high scratch resistance and good wear resistance.
- the inorganic binder preferably comprises one or more inorganic oxides, for example silicon dioxide.
- the binder preferably is a crosslinked inorganic material that covalently links the particles and the substrate.
- the inorganic binder may result after the cross-linking reaction and heating of the non-reacted binder, for example an alkoxy silane, an alkyl silicate or a sodium silicate.

- the amount of solids generally will be about 0.5 wt% or more, preferably about 1 wt% or more, more preferably about 2 wt% or more.
- the viscosity will be about 2.0 mPa.s or more, preferably 2.2 mPa.s or more and even more preferably about 2.4 mPa.s or more.

- the space where the glass plates are coated need not to be humidity controlled, and humidity between for example 30 and 80% is acceptable.
- the inorganic coating also is not sensitive to time delays between coating and curing.
- the organic UV curable coating is generally cured directly after application, although this is also not critical.
- the coating composition is applied to the article in a thickness eventually resulting in a thickness after cure of about 50 nm or larger, preferably of about 70 nm or larger, more preferably about 90 nm or higher.

- the comparative system consists of three optical layers applied progressively on both sides of the glass substrate by dip-coating.
- the type of glass used for the comparative sample has a low iron content and therefore has a higher spectral transmission and appear less green to the eye.
